Abstract

Poly(1,4-cyclohexanedicarboxylate)s, esp. poly(1,4-cyclohexanedimethylene-1,4-cyclohexanedicarboxylate), are prepd. from 1 relatively nonvolatile diol, such as 1,4-cyclohexanedimethanol, and cyclohexane-1,4-dicarboxylic acid by an esterification process in the presence of a catalyst, at .ltorsim.260°, which is a 2-step process, the second of which may be performed in the melt or in the solid state. A volatile diol such as ethylene glycol may also be present.
